How does combat work? What makes it different from combat in other MMORPGs?...

Some spells improve friendly units or weaken enemy troops.

Some players will move in circles (strafing) as you fight, especially Rogues. You'll have to learn how to run and rotate to combat this technique.

Organize your action bar very well...

Combat times vary depending on your level, the monster's level, class, equipment, spell usage and more.

Everyone loves emotes! Emotes are pre-generated macro sayings and actions that just require the proper code (text/name) to activate. To perform an emote type "/emotename". You can create your own emotes by typing "/em text".

Attention MAC Users: With a single button mouse, hold down the Command key on the keyboard while you click the mouse button to simulate a right click in the game.
